Patent application for an adjustable leveling block system for structures

ABSTRACT

An Adjustable Block Leveling System provides for the quick and easy leveling of heavy structures such as sheds, gazebos, decks, campers, trailers, temporary out buildings, portable buildings, portable offices such as used on construction sites or any permanent or temporary structure. It is also a handy tool to have around the house for many home uses. The System consists of a set of stackable blocks, with the top block being adjustable for height. Its height is adjusted by means of an angular split between the two halves of the block. Sliding one half of the block along the other half causes the height to vary because of the angle between the two halves. This system provides the exact height of blocks needed in order to easily and quickly level any structure, or to provide an adjustable support wherever needed.

The present invention relates to an adjustable block device for quick and easy leveling of heavy structures such as sheds, gazebos, decks, campers, trailers, temporary out buildings, portable buildings, portable offices such as used on construction sites or any permanent or temporary structure that needs to be supported and level.

The system is comprised of the following components:

The Leveling Block:

Drawing 1001, FIGS. 1 and 2 are side views and FIG. 3 is an end view of the Leveling Block.

A Leveling Block, which is a rectangular block fashioned out of material of any sturdy composition such as; wood, fiberglass, plastic, metal, concrete, brick, stone, laminate or any other solid material. The rectangular block is separated into two halves; a top half and a bottom half, as shown in drawing 1001. This is accomplished by slicing the block, lengthwise, on a slope (1), the angle of which would be determined by the size of the block. The size of the block will vary depending on the size and weight of the structure to be leveled.

Also shown in drawing 1001, the top half of the Leveling Block will be flat and even on its top surface (2), to make contact with the supported structure. The bottom surface of the top half (3) will be the sloping angle that mates with the bottom half of the block and is held to the mating bottom half of the block by means of a dovetailed tongue and groove along the sloping surfaces (4).

Also shown in drawing 1001, the bottom half of the leveling block will have a raised boss on the bottom surface (6) to allow it to nest with a mating Riser Block or Base Block. The Riser Blocks and Base Blocks will be described after this. The top surface of the bottom half (7) will be the sloping angle that will mate with the bottom surface of the top half (3). The bottom half of the leveling block will also have three holes (5) equally spaced along each side surface and angled sufficiently to allow them to exit into the sloping surface (7). These holes will be of a size sufficient to accommodate a brad, nail, or screw. When the leveling block is in place and adjusted to its final position, these holes may be used to drive a brad, nail, or screw through the hole into the mating top half of the leveling block to secure from any movement

The Riser Block:

Drawing 1002, sheet 1, FIG. 1 is a side view and FIG. 2 is an end view of the Riser Block. 1002, sheet 2, FIG. 1 is an isometric view of the Riser Block.

Another component of the leveling system is the Riser Block, shown in Drawing 1002—sheets one and two, of various heights which will match the length and width of the Leveling Block. The Riser block will be made of the same material as the Leveling Block, or can be made of any other material of sufficient strength and density. The Riser Block will have a raised boss on its bottom surface (8), and a matching depression (9) on its top surface to allow interlocking with other Riser Blocks, Leveling Blocks and Base Blocks.

The Base Block:

Drawing 1003 FIGS. 1 and 2 are isometric views of the Base Block, in two different sizes.

Another component of the leveling system is the Base Block, shown in Drawing 1003, of various heights which will match the length and the width of the leveling block. The Base Block will be made of the same material as the Leveling Block, or can be made of any other material of sufficient strength and density. The Base Block will have a matching depression on its top surface (10) to allow interlocking with Riser Blocks and Leveling Blocks. The bottom surface of the Base Block (11) will be flat and even to accommodate the surface it will rest on, such as the ground. The Base Block will also have a decorative chamfer, bevel, or beadwork (12) around the bottom perimeter of the Base Block to identify it as the bottom of the stack of blocks and the base of the system.

The Base Blocks and Riser Blocks are used to span larger gaps under a structure, with the Leveling Block on top of them to allow the adjustable feature of the Leveling Block to accomplish the final leveling of the structure. 

1. A Structural Leveling Block System comprising: An adjustable Leveling Block consisting of two equal halves, the block being split lengthwise at an angle and the two halves connected by a dovetailed groove, allowing the two halves to slide against each other and vary the height of the block.
 2. The invention of claim 1 further comprising a Riser Block of the same length and width as the Leveling Block and a height of any suitable dimension to attain the height required, and having a suitable configuration, with depressions and raised bosses, to allow it to nest with the other blocks.
 3. The invention of claim 1 further comprising a Base Block of the same length and width as the Leveling Block, and a height of any suitable dimension to attain the height required, and having a suitable configuration, with a depression on the top surface to allow nesting with the block above it, and a decorative chamfer, or bevel, or beadwork around the bottom perimeter of the Base Block to identify it as the bottom of the stack of blocks and the base of the system.
 4. That the use of this Leveling Block System to properly level heavy structures such as sheds, gazebos, decks, campers, trailers, temporary out buildings, portable buildings, portable offices such as used on construction sites or any permanent or temporary structure, will make the work of leveling the structure and maintaining the level condition of the structure much easier and faster than any other method available.
